The current API of this callback mixes responsibilities, including:
* validation
* transition checking
* processing (modifying) the configuration object.
These will have to be disentangled piece by piece, so for now, we'll
have "legacy" validate functions as well.

These conflicts were mostly related to autostyle improvements, with
one or two due to doxygen fixes.
This patch fixes an issue where the exit handler is not called for the
given process_t in case CreateProcessA() fails. This could, for example,
happen if the user tries to execute a binary that does not exist.

This patch removes a call to tor_assert_unreached() after execve()
failed. This assertion leads to the child process emitting a stack trace
on its standard output, which makes the error harder for the user to
demystify, since they think it is an internal error in Tor instead of
"just" being a "no such file or directory" error.
The process will now instead output "Error from child process: X" where
X is the stringified version of the errno value.

We used to have this function so that we could mark our initial
log-to-stdout as specifically temporary so that we would delete it
once regular logs were configured. But it's no longer necessary to
mark these logs as temporary, since we now use a mark-and-sweep
process to ensure that _all_ not-configured logs are closed when we
change our configuration.
Instead, this function will be the basis of a refactoring in how we
handle default logs.
In case of error, a negative value will be returned or NULL written into
first supplied argument.
This patch uses both cases to comply with style in the specific files.
A tor_vasprintf error in process_vprintf would lead to a NULL dereference
later on in buf_add, because the return value -1 casted to size_t would
pass an assertion check inside of buf_add.
On the other hand, common systems will fail on such an operation, so it
is not a huge difference to a simple assertion. Yet it is better to
properly fail instead of relying on such behaviour on all systems.

We have a getaddrinfo() implementation that we prefer, and a
gethostbyname*() implementation that we fall back on. Give them
both the same interface, and let them be called by the same name.
This is a preparatory step for making them both mockable.
